I'm on vacation in Flordia (not far from the original location of the Leaf!) so I haven't checked this group in a few days. Thank you all for your responses. I made an offer of $10,500 "all-in" (tax, tags, other stuff!). They're supposed to get back to me tomorrow. With a daughter starting to drive around this time next year and two boys following a couple years later, I like the idea of a car that doesn't go very far! Range-anxiety can be useful!
Regarding the battery, is it true that a battery degraded by heat will continue to degrade faster even after being moved out of the "hot" area? Interesting. Also, looking at battery capacities of various Leafs based on age, it looks like this vehicle is right on the curve for a four-year-old vehicle (https://pushevs.com/2018/03/20/nissan-l ... batteries/
Anyway, thanks for the comments! I'll let you know what happens.
